Truth seekers have gone into meltdown over three coded messages posted to the official WikiLeaks Twitter account. The tweets, posted on February 4, contain brief questions asking “what, where and when is #Vault7?” alongside seemingly unrelated images.

Pictures of the “Doomsday seed vault” in Norway, a German salt mine containing Nazi loot and a US Air Force jet engine are included in the tweets.

Now conspiracy theorists have gone into overdrive trying to figure out the meaning of the ambiguous messages.
